<p>The present invention provides a gusset bag (1) in which a sufficient area for indication can be retained on flat surfaces (2), paying attention to the structure of the gusset bag (1). The gusset bag (1) of the invention comprises flat surfaces (2,2) opposed to each other; and side surfaces (3,3) capable of being tucked in at creases by connecting the both ends of the flat surfaces (2,2); wherein a part of the side surfaces (3,3) is made transparent to form windows (9,9). Since windows (9,9) are provided on the side surfaces (3,3), it is possible to retain a sufficient area for indication in the flat surfaces (2,2), and observe the contents from outside. <IMAGE></p> |
